To ML w/wm it may concern:

Be it lniownthat l, CARL Gsoim NORnENs- SON, a-subiect of the King of Sweden and Norway, and a resident of Scane, Sweden, have invented a new and useful Machine for Cleaning Gas, of which the following is a specification.

My invention relates to a machine'for eX- I tion of my machine., and Fig. 2 is a vertical cross-section thereof.

My machine comprises a hollow 4shaft l, preferably horizontal, mounted in suitable Affixed to this hollow shaft are a number of radial vanes 23, arranged longitudinally of the shaft or with a helical twist. 'Preferably these vanes have perforations 4 therein, which perforations are more ellicient at the outer marginal portion of the vane. Mounted in the framework 2 concentrically with the hollow shift is a cylindrical casing 5, which incloses said shaft an d une vanos thereon. Mounted inside of this casing is a perforated shell Geloscly adjaiient to the cuter margins of the venes; Preferably this shell is of conical forni tapering from the inlet end to the outlet end, and the vanos likewise taper to conform to, the shell. rangement the annular space surrounding the ertorated shell increases in width from the inlet endtoward the outlet end.

The hollow shaft 1 is closed at one end and at the other end is connected by a pipe 7,controlled by a valve 8, to any suitable source of water-supply. The portion of the shaft within. thc casing has radial perforations 9, whereby the water from the source of supply may pass into the interior of the perforated shell. 6. These perforations are designed to deliver small streams of water, but should not l be so .small as to be liable to be clogged by the deposit of tar thereon. At its lowerrnost 'portion the casing 5 is njovided with a pipe l0 for the outflow of water, and outlet- The Casing; 5 has end plates l2 thereon, which are By this arprovided with central openings i3, connnunicating with chambers 1 4 15 in the fra1nework. One of these last-mentioned cha1nbers 14C is connected to a gas-producer, and the other' chamber l5 communicates with a gas tank or holder. The shaft l is provided with any suitable means for driving it-as, for instance, with a pulley 16, adapted to be driven by a belt from any suitable source of power.

The operation of my device is as follows: The shaft l is set in motion and the valve S is opened. Thereupon water runs from the source of supply through the pipe 7 and the hollow shaft l, from the perforations in which it issues in small streams into the interior of the perforated shell 6. The water thus delivered inside of the perforated shell runs through the perforations therein into the space surrounding said shell and thence issues through. the outlet-pipe l0 into the well 11. rlhe gas from the producer passes through the chamber 14 ydirectlyl into the interior of the perforated casing 6, and thence passes through the openings in said casing into the space surrounding said casing, and thence into the chamber l5 at' the opposite end of the framework, and thence into the gas tank or holder. The smali streams of water issuing from the shaft effect an initial distribution of the water with some degree of uniformity throughout the perforated shell and the gas therein, and the vancs of the rapidly-rotating shaft act as beaters to break the Water into spray audeffect the thorough conirningling of the water and the gas. This function of the'beaters increased by the perforations therein. The effectiveness of the beaters depends upon the density of the gas in. 'the casing and the velocity of the beaters. By givingr the vanes a helical` twist the density of the gas may be increased, and by increasing the width of the vanes at the inlet end the velocity of the marginal portion of vthe beater at the inlet end is greater than at the outlet end. As the centrifugal action throws the toward the circumference and the bea tiner action is principally. at theouter portion of the varies, these arrangements tend to utilize thefull length of the casing. in consequence of the space surrounding the perforated easingl increasing in width from. the inlet end to the outlet end there is also a tendency for the current of gas to be dis-- IOO having radial Ion said framework and surr heater-blades, a perlorated shell inside of said tributed throughout the full length of the shell. In consequence of these arrangements the particles of tar carried in the gas are. cooled and taken up hy the water in the forni of a mixture which runs out thro ugh the ontlet-pipe into the delivery-well. ln ilic delivery-well the tar gradually' separates from the water and rises to the surface thereof. Either continuously or from time to time the tar is drawn off from the surface of the water in the delivery-well, and thc water is drawn off from a point below the level of the tar,

It is noted that the hearings of the hollow shaft are kept cool hy the cold water ilowin therethrouO-h.

What I claim is- 1. A machine for removing tar and solid matter from gas consisting of a framework, a hollow shaft mounted in said framework and having radial perforations therein and have ingAbeater-hlades thereon, a easingr mounted on -said framework and surrounding said beater-blades, a perforated shell inside ol' said casing,- an inletepipe connected with said hollow shaft and an outlet-pipe connected with the lower end of said casing, said machine heing' provided with two passage-ways one ol' which opens into the interior of said shell and the'second of which opens into said casing' at apoint outside of said shell.

' 2. A machine for removing tar and solid matter from gas consisting` of a framework, a hollow shaft mounted in'said framework and perforations therein and having beater-blades thereon, a ci sing mounted oundinil said O. TTI

casing adjacent to the edges of said blades, aninletpipe c 'inected with 'said hollow shaft and an outlet-pipe connected with the lower.' end of said casing, said machine having two passage-ways oneof which opens into thc in terior of said shell and the second of whichL opens into said casing at a point outside of said shell, and said heater-blades boing wider at the inlet end than at the outlet end oll said casing.

3. A machine for removing tar and solid matter from gas consisting of a framework, a hollow shaft mounted in said framework and having radial perforations therein and hav-- ing beatereblades thereon, an elongated casing mounted on said framework and surl rounding ceder-lr said 4heater-blades, an elongated perforated conical shell inside of said casino, an inlet-pipe connected with said hollow shaft and an outlet-pipe connected with the lower end of said casing, said machine havingtwo passage-ways one of which opens into the interior of said shell and the second of which opens linto said 'casinof at a point outside of sind shell, vand said heater-blades having their outer. margins inclined. to conform 'to the inii surface ofthe conical shell.
